I also use Sonar for some stuff but I found Reaper much easier for this type of thing. As I said in Reaper set the project speed to 104.862 and pull in the file 105BPM drums. Then change the project speed to 150. It will change to 150 and stretch accordingly. Then the second file can load normally (it is already 150). Sonar does not do the same thing as far as I know.

Yes shifting all transients is a huge job. I’ve been there and done that. That is why once I started manipulating audio files in Reaper I found it far easier than Sonar. I therefore kept Reaper as well as Sonar. I prefer Sonar to Reaper for midi (cntrl F1 gives a heap of scripts to manipulate midi in Sonar)

You could download the trial of Reaper. Convert the offending file, render it and pull it into Sonar to do the rest. Very quick. Just a thought.
